This is your system
Hardware -> Mac OSX -> VMWare -> Windows 8 -> Rhino for Windows
VMWare and Parallels are both Windows emulators.
They actually work by abstracting the hardware. The Rhino application is programmed to go directly to the hardware. The way you have your system configured with VMWare, the hardware is not accessible like it is on a standard Windows system. This is why when running Rhino on VMWare there are typically problems with video and pointing devices.
In your configuration, Rhino 5 for Windows is installed under VMWare which not a supported configuration.
See System Requirements here.
So what works? The Bootcamp drivers from Apple will allow the computer to boot directly to Windows. So the program heirachy looks like this:
Hardware -> Windows 8 -> Rhino for Windows.
It is a Windows computer when it is Bootcamped to Windows.
This is the only reliable and stable was to configure your Rhino 5 for Windows system.
Please use the under development MacRhino for modeling when you are booted under OSX.
Hope this helps.
